Mayor Will Flanagan raised thousands of dollars more than his five opponents put together, garnering nearly $108,000 in donations since Jan. 1 of this year in his bid for a third term in office.

It’s a far cry from the $0 reported by William Grinvalsky, $285 reported by Joao Costa, $1,072 gathered by Richard Renzi and $3,830 reported by Joseph Carvalho, according to pre-primary reports from the Massachusetts Office of Campaign and Political Finance.

The OCPF website did not show reports submitted by candidate Mike Raposa. The deadline for filing was Tuesday.

The pre-primary report filed by Flanagan lists 544 itemized donors totalling $101,340 and $7,215 in unitemized receipts, representing donations of less than $50.

From Jan. 1 to Aug. 23, Flanagan spent $72,912, with many of the expenditures donations to nonprofit organizations like the Corky Row Club and the Fall River Police Relief Association.

His top two expenditures in his campaign so far were for two events at Venus de Milo restaurant in Swansea, costing $12,537, and a payment to Riccardi’s Catering for $8,286.

Among the donors to Flanagan identifying their places of employment, 85 donations are from city and school workers, and 11 donations are from staff at the Fall River Housing Authority. Flanagan is also chairman of the Fall River School Committee and appoints three members of the Housing Authority board.

Among the many local business owners listed in Flanagan’s filing is a $400 donation from Paula Ruggiero, a Barrington, R.I., real estate agent for Ruggiero Properties and wife of businessman Joseph Ruggiero, who recently bid to purchase the city’s former police station on Bedford Street at the mayor’s request. Ruggiero is also the owner of First Ford, previously owned by local resident Fernando Garcia, and most recently sold the Regatta restaurant on the city’s waterfront.

Ruggiero is also identified in federal court documents obtained in Rhode Island by The Herald News as a member of the New England La Cosa Nostra and an associate of the former mob boss 84-year-old Luigi “Baby Shacks” Manocchio, who was convicted in May 2012 and sentenced to 5½ years in federal prison for shaking down strip club owners in Providence.

Flanagan did not immediately respond to phone calls requesting comment.

Flanagan’s success at fundraising for this campaign is a repeat of his bid for mayor in 2010, where he raised $118,466 in campaign donations.

After that successful bid for mayor, Flanagan was cited by the OCPF for 21 violations for excessive contributions. Flanagan did not face any penalties for the indiscretion because his campaign committee recognized the violation prior to being notified by OCPF and refunded the excess contributions.

The preliminary election is Tuesday, the same day as the special election for the 6th Bristol Representative District seat.
